Thermal defluorinated phosphates based on phosphorites of the Central Kyzylkum

Abstract

This study investigates the defluorination of phosphates derived from the Central Kyzylkum phosphorites through heat treatment processes. The research focuses on the thermal decomposition of fluorine-containing compounds in the phosphorites, aiming to produce defluorinated phosphates suitable for industrial applications. The influence of various temperatures and time durations on the efficiency of fluorine removal is examined. The study also explores the resulting chemical composition and potential uses of the defluorinated product, particularly in fertilizers. Results indicate that optimal heat treatment conditions can significantly reduce fluorine content, enhancing the utility of Kyzylkum phosphorites in various sectors.
